The fighters will meet this Saturday (26.04.25) in a clash with echoes of the rivalry between their fathers Nigel Benn and Chris Eubank during the 1990s and Benn explained that he is desperate to get the better of an opponent he hates.
The boxer told Sky Sports: "We're focused on the future. We're focused on finishing what we started. I hate what he stands for. I hate who he is as a man, what he's chasing.
"Just him as a man personally for reasons that aren't public, personal reasons, between me and Chris that he's fully aware of as to why I really dislike him.
"A fight's a fight. Obviously there is interest with the history of our dads, us being our fathers' sons, the apple doesn't fall far from the tree.
"But I think there's a big personality clash, the controversy, the adversity, it sells. It doesn't change the outcome of April 26 and what I'm going to do to him."
The duo had been due to fight in 2022 before Benn failed two voluntary drug tests and the British welterweight pugilist is hellbent on ending the career of Eubank Jr - who stands on the brink of challenging for a middleweight world title.
He said: "It was a fight that just seemed to never go away. It was a fight that the public demanded and commercially made a lot more sense.
"When he loses he has to retire. I don't understand why at this stage of his career he'd choose to fight a welterweight over a world title. I can drop down and go and get my world title.
"But, for me, he's chasing one thing and that's the difference between me and him."
